Background technology
At present, in the wild during work high above the ground, common shaft tower has 10 meters 30 meters high, and in overhead transmission line, commonly used traditional safety rope and speed difference catching device, carry out safeguard protection to operating personnel.
But, when there is falling accident in electric power work high above the ground, existing one people of two kinds of safety rope user cannot be carried out saving oneself.In this case operation team other staff must be relied on to come to help rescue, and this not only to affect other people work, also to employ other and rescue people's execution of instrument and rescue people, namely time-consuming, requires great effort again.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of time strand formula automatic recycling device, purpose be can when work high above the ground falling accident occurs the very first time quickly save oneself, and it is safe and reliable, staff can be eliminated when there is falling from high altitude, cannot the trouble and worry in backtracking face, increase staff's personnel safety factor.
The technical solution adopted for the present invention to solve the technical problems is:
Returning strand formula automatic recycling device, it includes inner disk and seat belt；Mainly it is made up of anti-drop system and back twisted system；Wherein, inner disk connects the first mainboard and gear by main shaft side, and inner disk opposite side connects the second mainboard by main shaft；The side of inner disk is connected to card hammer；It is connected to internal gear inside first mainboard, outside the first mainboard, is connected to trip and spanner；Inner disk is provided with seat belt.
Described inner disk is H type collar plate shape structure.
The first described mainboard is for being with reeded concave structure steel plate.
The second described mainboard is plane steel plate structure.
Described card hammer is imitative hammer body structure, is provided with two.
Described trip is the handle with draw-in groove.
Described spanner is the handle with draw-in groove.
Described internal gear is made up of multiple internal tooths.
Described gear is made up of multiple external tooths.
Described main shaft band buckle steel axle.
Advantages of the present invention and providing the benefit that: owing to the present invention is mainly made up of anti-drop system, back twisted system and spring system and seat belt, step in high-altitude before tower operating personnel climbs shaft tower, first incite somebody to action back strand formula automatic recycling device and tie up to operating personnel predecessor's waist, stepping on tower again to the scope of operation, now the other end of the present invention can be suspended on the firm main material in top by operating personnel.Therefore, when unexpected falling, operating personnel can pass through returning of main shaft is twisted, it is possible to easily makes self to return to normal work platforms, works on, can eliminate the trouble and worry of work high above the ground personnel completely.Operating personnel can save oneself at once.Do not need other staff to succour.
The present invention has stronger practicality, and makes operating personnel's security performance when work high above the ground be significantly improved.Also there is simple in construction, advantage esy to use, safe and reliable, substantially increase the Personal Safety of work high above the ground personnel, be suitable in field of aerial work popularization and application such as electric power.
Below in conjunction with specific embodiments of the invention and accompanying drawing, the present invention is described in detail in.

In figure: inner disk 1, card hammer 2, internal gear 3, main shaft 4, the first mainboard 5, gear 6, trip 7, spanner 8, the second mainboard 9.
Detailed description of the invention
As shown in Figure 1, the present invention is a kind of time strand formula automatic recycling device, mainly formed by by anti-drop system and back twisted system, including inner disk and seat belt, specifically being connected the gear 6 with reeded concave structure steel plate the first mainboard 5 and back twisted system by the inner disk 1 of H type collar plate shape structure by main shaft 4 side, inner disk 1 opposite side connects the second mainboard 9 of plane steel plate structure by main shaft 4；The side of inner disk 1 is connected to two imitative hammer body structure card hammers 2 relatively by bolt spring is fixing；It is connected to internal gear 3 inside first mainboard 5, outside the first mainboard 5, is fixedly connected with card hammer tenon 7 and spanner 8 by bolt, spring；On inner disk 1, dish has anti-drop system seat belt.
Wherein, the theoretical foundation of anti-drop system reason is mainly according to Newton's law and centrifugal inertial force.Anti-drop system structure is as follows: anti-drop system internal structure mainly full part has: inner disk 1, card hammer 2, internal gear 3, main shaft 4, the first mainboard 5, the second mainboard 9, concrete structure is as shown in Figure 2.First mainboard 5 and the second mainboard 9 are to be connected fixing double-deck empty frame plate by upper and lower 3 screws, and it is back that strand formula automatically reclaims safety device and closes the heart, is main load-supporting part.
Inner disk 1 is primarily used to volume seat belt, and inner disk 1 is connected on the first mainboard 5 by main shaft 4 by it, and inner disk 1 at the first mainboard 5, can rotate freely in the empty frame of double; two one-tenth of the second mainboard 9 composition.
Card hammer 2 is two imitative hammer bodies, and it is fastened on inner disk 1 by screw spring, and when inner disk 1 rotates, card hammer 2 rotates with.
Described internal gear 3, is made up of many internal tooths, and it is also be screwed on mainboard 5, and card hammer 2 can rotate in internal gear 3,
Described main shaft 4, a band buckle steel axle, also it is that whole device closes the heart, is also connected in mainboard 5, on inner disk 1, can rotate freely.
Anti-drop system self-locking manner is: inner disk 1 is linked with seat belt by main shaft 4, card hammer 2 is fixed on inner disk 1, internal gear 3 is fixed on the first mainboard 5, and when seat belt stretches out, card hammer 2 starts to rotate in internal gear 3, when seat belt rotary speed is accelerated, inner disk 1 rotary speed is also accelerated, and card hammer 2 speed are also with inner disk 1 also spin even faster, now, card hammer 2, while rotary speed is accelerated, produces the centrifugal inertial force that is the center of circle with " 0 ' ".When seat belt speed continues to strengthen, the centrifugal inertial force that card hammer 2 is the center of circle with " 0 ' " also strengthens, card hammer 2 is outwards dished out with " 0 ' " for the center of circle simultaneously, at this moment card hammer 2 is just engaged mutually with internal gear 3 internal tooth, internal gear 3 and mainboard 5 are fixed together, serving the effect of self-locking, seat belt also stops stretching out, and also just serves the effect of safety rope.
The main portion compositions such as heretofore described back twisted system structure is: by gear 6, trip 7, spanner 8, spanner spring, trip spring.Wherein, gear 6 is fixed on main shaft 4, and trip 7, by spring, is bolted on the first mainboard 5.Spanner 8 passes through spring, is bolted on mainboard 5, and structural representation is as shown in Figure 3.
Its middle gear 6 is made up of many external tooths, and it is bolted on main shaft 4, is rotate with main shaft 4 and rotate.Trip 7 is a handle with draw-in groove, and it is fixed on the first mainboard 5 by bolt trip spring, is used to restriction and controls the rotation of gear 6, and it can also rotate.Spanner 8 is also a handle with draw-in groove, and it is fixed on the first mainboard 5 by track wrench spring, and it can also rotate, and is used to restriction and controls the rotation of trip 7.
In the present invention, back twisted system operation principle is: when user uses of seat belts, by cocked for trip 7 next, at this moment spanner 8 is risen by spanner 8 spring effect appliance for releasing single and blocks trip 7, gear 6 just can rotate freely, when emergency occurs, seat belt is pinned by anti-drop system, makes seat belt not rotate.At this moment, we are by cocked for spanner 8 next, and trip 7 is retracted by trip 7 by trip spring effect, and is seized gear 6, and then, main shaft is rotated back by we with the spanner carried with, and user returns strand and arrives normal work platforms.
